BRAKE-OPERATING MEANS FOR PHONOGRAPHS.

Specification of Letters Patent.

Patented Aug. 2d, 18915.

Application filed September 16, 1914. Serial No. 861,977.

To all whom, it mag con cern Be it known that I, WALTER J. AUGUSTIN,

a citizen of the United States, and airesident' of the city of Fond duLac, county of Fond du Lac, and State of Wisconsin, have 1nventedcertain new and useful Improvements in Brake-Operating Means forPhonographs, of which the following is a specification.

My invention relates to phonographs, and more specifically to mechanismfor actuating the brake member of a phonograph.

The object of my invention is the production of a mechanism of thecharacter mentioned through the medium of which the brake member of aphonograph may be readily and easily actuated so as to effect stoppingof the sound-reproducing mechanism of the phonograph immediately uponthe completion ofthe rendition of a record.

A further object is the production of a device as mentioned whichw-i-l-l-be of simple construction and eficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in.

which,

Figure 1 is a top plan view ofa fragment of a conventional phonographequipped with mechanism embodying my invention, and Fig. 2 is anenlarged section taken on line w;v of Fig. 1. v

The preferred form of construction as illustrated in the drawing isapplied to a phonograph of conventional. construction comprising asshown a casing 1 wherein is mounted the actuating mechanism of themachine, a rotatable record support 2 being provided at the upper sideof the casing 1 for supporting the record 3.

A starting lever 4 is shown through the medium of which thesound-reproducing mechanism is released for operation, as will beunderstood by those skillediin the art.

Arranged adjacentthe starting lever 4 is the brake member 5 whereby.thesound-re producing mechanism is 'brou ht to a stop after therendition of a recor The brake member, in the operation of the machine,at the present time, is automatically actuated by means. of an arm 6.which is fixed to an oscillatory post 7, the latter being directlyconnected with the sound box or stylus of the machine so. that as thesound box or stylus traverses the record, the free end of the arm 6 isgradually moved toward the member 5, contacting therewith so as to causestopping of the machine when the nee-- dle of the sound box or stylushas reached a position in'which the same engages in the innermostconvolution of the groove of the record.

All records are not of the same length, so

that in the case of a short record or one which does not occupy theinner portion of v the groove or say the last ten or twelve convolutionsthereof, the sound-reproducingvv mechanism continues to operate for acon-,

siderable time until the arm 6 contacts with the member 5 which does notoccur until the needle reaches the innermost convolu of thisdisagreeable sound after the completion of a record that this inventionis designed. With this object in view, an attachment is employed forconnection with the actuating arm 6. *This attachment com- 7 prises ascrew 8 in threadedconnection with a boss 9 termed at the upper side ofa band or strap 10 which embraces said arm adjacent the outer endthereof, the member '10 being clamped to said arm by means of a screw11. The screw 8 is so positioned that one end thereof is adapted tocontact with the outer end of brake member 5. Through the threadedconnection of said screw with the boss 9, it is clear that the formermay be'adjusted as desired to accommodate records of various lengths andin the event of the screw 8 not having been previously set,

if it is desired to immediately stop the sound-reproducing mechanism,after the rendition of a record, the screw 8 may: be

manually adjusted. in order to cause the.

While l have il ustrated and described the I my invention into effect,this is capable variation and modification without departpreferred formof eonstruction for carrying ing from the spirit, of rthe invention. zI,therefore, donot wish to be limitedto the precise details ofconstruction set forth, but

desire to avail myself of such variations and modifications ascomewithin the scope of the appended claims.

Having described invention what-I claim as new and desire to securebyvLetters Patent is:

1. Thecombin'ationin a phonograph of a rotating member; a brake memberfor cooperation with said rotating member; an actuating member"adaptedfor automatic movement into engagement with said brake toactuatethe same, astrap embracing said actuatingmember; a screw forreleasably clamping said strap to said actuating member;'. and a screwin threaded connection with said strap for engagement with said brakemember, said screw being manually adjustabletoward and from said brakemember, substantially as described.

2. The combination with aphonograph of a rotating member; a brake memberfor co operation with said rotating member ;.an actuating member adaptedfor automatic movement into engagement with said brake to actuate thesame, a strap embracing said actuating member; a screw for releasablyclamping said strap to said actuating member; a lug provided on andprojecting from said strap; and a screw in threaded connection with saidug for engagement with said brake member, said screw being manuallyadjustable toward and from saidbrake member, substantiallyas described.

3. The combination in a vphonograph of a rotating member; a brake memberforceoperation with said rotating member; an actuating member adapted.for automatic movement into engagement with said brake member to"actuate thesame, a strap having a substantiallyrectangular openingtherein for snuglyembracing said actuating member; a screw connectingthe ends of said WALTER JOHN.
